PURPOSE

• Develop a modeling tool to support INLS OPEVAL
• Include latest MPSRON load plans and squadron
  remix
• Supplement to Operational Testing
• Provide a tool to measure environmental
  conditions effect
• Develop IAW SECNAV 5200.40A
• Validation and Verification required
• Certification by Program Manager and OPTEVFOR
• Transition as Fleet tool for training, exercises,
  operations

INLS Capabilities Analysis Tool (ICAT)

• STATEMENT OF WORK
• Develop an INLS throughput modeling tool that
  will allow the planner to examine the dynamics of
  INLS Developmental Testing and Operational
  Testing.
• Identify possible bottlenecks and problems
• Assess the impact of a dynamic event
• Plan contingencies for use during execution
• Reduce time required for Developmental and
  Operational Testing
• Transition to a tool for the operating forces

INLS Capabilities Analysis Tool (ICAT)

• MS Windows-based
• Provides a modeling and simulation capability to
  provide system engineering insight across flows.
  It consists of
• A simulation engine
• Libraries of graphical elements of integrated
  spreadsheet and project management tools (for
  timeline analysis), and
• MS Access Database
• Visualization for easy understanding and
  presentation
• Discrete Event Simulation of INLS offload
  timeline
• Algorithms are visual and do not require an
  understanding of a computer software language
• No license or fee for runtime version of TopView

Specifics of the ICA Tool

• Developed using Extend/TopView modeling and
  simulation tool
• Map area established by entering latitude and
  longitude of map corners.
• Each element has a Lat/Long location for
  computing distance from other elements.
• Elements are updated after they move.
• Inventory represents the available elements that
  can be used in the model.
• Lighterage and Ships can be activated from
  inventory and deactivated back to inventory
  before a simulation run.
• Performance measures are computed by the
  simulation
• Multiple Trial Monte Carlo Execution for Metrics
  Data Collection

Data Base

• MS Access
• All simulation data parameters can be changed in
  MS Access not in the model.
• Changing data values
• Cargo Quantities
• Cargo Transfer Rate
• Environment
• Capacities
• Reviewing data
• Data Collection for Performance Measure
  calculation.
